How to Use the Enzyme-Catalyzed Reaction Calculator?

Using our advanced calculator is a breeze! Let's break down the terms used:

• Kinetic Model - Select the desired kinetic model based on your enzymatic reaction type.
• Substrate Concentration [S] - The initial concentration of the substrate in the reaction.
• Enzyme Concentration [E] - The concentration of the enzyme in the reaction.
• Turnover Number (kcat) - The number of substrate molecules an enzyme can convert into product per unit time.
• Michaelis Constant (Km) - The substrate concentration at which the reaction rate is half of Vmax.
• Inhibition Constant (Ki) - Required for inhibition models, representing the inhibitor concentration needed to reduce the enzyme activity by half.
• Time - The total time of the reaction.

What is an Enzyme-Catalyzed Reaction?

Enzymes are nature's catalysts, accelerating chemical reactions within living organisms by lowering the activation energy. Enzyme-catalyzed reactions are fundamental for sustaining life, facilitating various biological processes.

A basic representation of an enzyme-catalyzed reaction is: ( E + S \xrightarrow{k1} ES \xrightarrow{k2} E + P ), where (E) is the enzyme, (S) is the substrate, (ES) is the enzyme-substrate complex, and (P) is the product.

Enzyme-Catalyzed Reaction Formulas

Our calculator utilizes various kinetic models, each described by specific formulas:

Michaelis-Menten Model: V = \dfrac{V_{max} [S]}{K_m + [S]}

Competitive Inhibition Model: V = \dfrac{V_{max} [S]}{K_m (1 + \frac{[I]}{K_i}) + [S]}

For other inhibition models, additional equations and constants are employed, providing a comprehensive analysis of enzyme-catalyzed reactions.
